Having had to do this activity many times in the past - I believe your best bet for commands are the following:
"show spanning-tree vlan x"
- This command will show you where the VLAN is configured on a currently active interface. For example - is it configured on a trunk uplink to another switch? Or an access port to a PC?
"show vlan brief"
- This command will show you which Access ports the VLAN has been assigned to. (Even if they are not currently active interfaces).
"show int trunks"
- This command will show you the list of VLANs that are allowed on a trunk. This will not only show you the "configured" list of VLANs, but also the list of VLANs that can actively participate on the trunk (because sometimes VTP pruning takes VLANs away without us ever knowing!)
The combination of these 3 commands should allow you to decide whether the particular VLAN is needed on any one switch and or if it needed on any downstream switches that may be relying on the switch as a middle-man.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
